Hi Crazy,
Thanks for the answer. Right after I posted I started looking around for current info about Visual Studio.
In a chat session with a MS employee on their VS webpage, the employee directed me to the free download too!
I downloaded it, copied the AppGameKit template for vs2015 and it worked - straight out of the box. That was a novel experience.
Anyway, it looks like you have to jump through some hoops to build for android in VS. I found an article from 2011 that described how to configure building for Android from inside VS.
(http://www.gavpugh.com/2011/02/04/vs-android-developing-for-android-in-visual-studio/ - excellent article.)
Now I'm wondering if there is something provided by MS to do it, after all they are claiming cross-platform builds with this.
If there is, it isn't obvious. I'll have to dig deeper, unless someone can direct me to it.
